Poets say science takes away from the beauty of the stars - mere globs of gas atoms. Nothing is 'mere'. I too can see
the stars on a desert night, and feel them. But do I see less or more? The vastness of the heavens stretches my imagination - stuck on this carousel my little eye can catch one-million-year-old light. A vast
pattern - of which I am a part... What is the pattern or the meaning or
the why? It does not do harm to the mystery to know a little more about it.
For far more marvelous is the truth than any artists of the past imagined it. Why do the poets of the present not speak of
it? What men are poets who can speak of Jupiter if he were a man, but if he is an immense spinning sphere of methane
and ammonia must be silent?

"In crossing a heath, suppose I pitched my foot against a stone and were asked how the stone came to be there, I might possibly answer that for anything I knew to the contrary it had lain there forever; nor would it, perhaps, be very easy to show the absurdity of this answer.”

"Yet why should not this answer serve for the watch as well as for the stone? For this reason, and none other, viz.,
that when we come to inspect the watch, we perceive what we could not discover in the stone, that its several parts
were put together for a purpose."
